First, the flow principle and purpose submersible jet aerator generated by the submersible pump through a nozzle to form a high-speed water flow around the nozzle to form a negative pressure of the intake air, and water are mixed mixing chamber, resulting in a diffusion tube flared gas mixture of water flow, high-speed jet out many bubbles entrained flow vortex agitation in the larger area and depth of the waters, complete aeration, and the shaft power does not change with the depth of the potential changes, intake air can be adjusted. Because of this, diving jet aerator can be varied in a larger application pool level. Second, the main features: 1, compact submersible jet aerator, small footprint, easy installation. Aerators by submersible sewage pumps, aerator and into the trachea of ??three parts, compact, small footprint; addition, aerators offers two installation, easy to install, easy to maintain. 2, diving jet aerator aeration high efficiency, wide range of applications. Due to its high-speed jet stream state, liquid gas mixture sufficiently, oxygen absorption rate, high power efficiency. Higher efficiency than conventional aeration process 3 to 4 times, aeration time can be significantly reduced, and for a variety of wastewater treatment, including plug-flow aeration tank, mixing aeration tank, extended aeration ponds, oxidation ditch, oxidation ponds. 3, diving jet aerator system is simple and high reliability. Without blowers and other equipment, the system is simple, in addition to inhale estuary, and the rest were submerged operation, low noise; aerators use special tape cutting submersible sewage pumps, high efficiency without clogging, safe and reliable equipment, long service life. 4, diving jet aerator investment and operating costs low. Since the jet aerator is suitable for deep aeration tank, reducing the footprint, the system is simple, save investment costs, high processing performance, save operating costs. Third, the use range: QSB series submersible jet aerator is feedwater pretreatment and biological wastewater treatment process in special aeration equipment for aeration settling basin, pre-aeration tank, oxidation pond aeration and agitation, etc.; submersible jet aerator can also be used for breeding pond water aerobics and landscape conservation; submersible jet aerator process can also be used for water front in addition to iron, manganese process can also be used for high-rise building water replenishment cycle process. Fourth, the applicable conditions: QSB can lower self-priming type deepwater submersible jet aerator in normal continuous operation under the following conditions: a maximum medium temperature does not exceed 40 ° C; 2, PH value of the medium at 5-9; 3 , medium density not exceeding 1150kg / m3. Fifth, the model representation: Note: The table is the ability to intake air and oxygen under standard test conditions (20 ° C water temperature, barometric pressure 101.325kPa), aerators diving depth 3m, test medium is water. In moderate sewage, gas capacity can be increased coefficient 0.85 as a design basis. Six, selection and installation of: ~ ~ submersible jet aerator product selection assistance required by the Company, the user should provide relevant data pool type, dielectric properties, the required intake air, diving depth, in order to design and provide the Company quality equipment to better meet the needs of users. QSB type deepwater installation in the form of self-suction submersible jet aerator has auto and mobile two. Auto-mount is the aeration device and a dedicated base is fixed at the bottom of the pool, installed in the pool support block matching top, so that the two are connected by rail, submersible pump bracket coupled with a specific decline in the end after a good seat along the rail exports position, through the pump weight, the automatic coupling and sealed. Auto-installation without having to install or maintenance personnel to upgrade and install into the sump pump. Mobile installation is self-priming deepwater submersible jet aerator installed in the bottom of the pool, relying on weight positioning, with the installation location may change, flexibility, and low cost.
